I like seeing `Board is replaceable`. At the end of the day, aren't we all replaceable?

## Copy to the NAS
Keep the ZIP. Maybe it was automatically decompressed for you, maybe not. Either way, it's simpler to move one file than five. I kept it easy and used `scp` to move the whole ZIP downloaded from Supermicro. Write the file to `/tmp`.

## SSH to host
The rest of these steps will be done via SSH. Connect to the NAS. You may have to enable SSH on TrueNAS if you haven't done so before; while it's probably possible to run this from the GUI-shell it's safer to stick within the terminal.

## Start tmux
Sadly for my muscle memory, `screen` is no longer included in TrueNAS SCALE. You have to switch to `tmux`. Thankfully the basics aren't too hard. Start a session with:

Arguably, this is for the best, since `tmux` sees active development. TrueNAS wants to function like an appliance, even if it is a full Linux system. Just because you can, doesn't mean you should, and iXsystems strongly discourages installing new packages just because you're a dinosaur and don't want to change. Now excuse me while I chase some kids off my lawn.

## Extract
You'll need to unzip and then untar, since the main file is a ZIP. Once unzipped, move into the new directory. Then untar the Linux files (`tar -xvf archive.tar.gz`) and unzip the BIOS file. (`unzip archive.zip`) Why is this a convoluted series of compressed files? Excellent question. The answer lies in what I suspect are a series of cobbled-together scripts that take a bunch of build system outputs and glue them together like a software matryoshka doll. Would it be easier if it was all just one ZIP file? Yes, but bandwidth is cheap now, so we compress the compressed despite it offering no benefits instead of compressing _everything_ with a single compression pass at the end.

Moving along.

## Remount /tmp
Another arguably good win for security is `/tmp` is now mounted with the `noexec` flag set. You can't run the updater from `/tmp` even as root. Thankfully, this is easy enough to temporarily ~fix~ bodge. Simply remount the filesystem: `sudo mount -o remount,exec /tmp`

This _will_ be undone once you restart the system (and everything in `/tmp` will go away too) but that's fine! Now we don't have to remember to undo anything to make it secure again, especially because the system requires a reboot at the end of the flashing process.

## Update the BIOS
Now we're ready to flash the BIOS. Your system is on stable power, preferably a UPS, and your SSH session is being run through tmux. This should prevent issues from a dropped connection or flickering mains power resulting in a half-flashed BIOS, resulting in much whisky (and recovery tools) being needed.

Simply run `sudo ./sum -c UpdateBios --file /tmp/path/to/BIOS.bin`

The process can take a little while. Don't be surprised if it takes 10 minutes. The percentages should slowly increase.
